At the top level of international competition, there is very little difference between the various jumpers and who performs best on the day wins.
Often, there has been serious concern and debate over whether I might flop in international competitions. But most of my best performances have come in major events and the best record of 6.83m was achieved at the 2004 Athens Olympics.
We are still learning and constantly experimenting with various sprinting techniques to see what can provide the best performance.
